My first experience with recapping

[category_five]

I recently recapped my first motherboard and it worked great.

The symptom was a dead board. No power, no post. I wasn't sure if recapping would solve it, but since the board was an old unique form factor buying new wasn't an option. I was relieved when it booted fine with new caps.

One issue I encountered during the process -one green and gold sanyo's dielectric had leaked and it must have made some kind of temperature resistant alloy when I desoldered the cap. Clearing the left over solder from the hole was impossible with either an 808 desoldering gun or with a copper braid. I tried like 5 times adding and removing solder from it. I ended up just sticking a dentist pick through it to clear the hole.

But anyways.

Thanks badcaps guys for bringing this repair technique to my attention.

Reading through this forum more, it looks like I dodged a bullet on ESR with the replacement ZLH Rubycons I bought.
Too bad I don't have an ESR meter to have checked if they were counterfeit.

Adding new solder\flux when desoldering can help. If the old solder is dirty then heat transfer into it will be limited, and it will be harder to work with.

Or you have just discovered why working on multilayer boards with big internal ground\power planes can be annoying.

Agent24 - Notice the date in-between the posts. I think he was just coming back to say hello.
